Figure 23: Participants during the first session of the Water Accounting training.

The session provided participants with an in-depth understanding of SIWA+ input data

requirements, including the importance and need for bias-correction of remote sensing data
with observed datasets where possible, and the significance of discharge data within the

framework. Participants also learned about how the VegET hydrological model was used for

simulating river discharge for continental Africa as well as how it is was validated using in-situ
based river discharge mostly from the GRDC website. The validation of the eight remote

sensing (RS) rainfall products used in the Incomati basin and their performance was explained,

leading to the conclusion of ARC and RFE as the best-performing products, capturing both wet

and dry rainfall years.

WA Visualizations: IWMI Geoportal, Dashboards
The morning session concluded with an introduction to visualization of WA output data led

by Dr. Mansoor. Illustrations of visualization of WA+ results included IWMI Geoportal

(https://iwmi.africageoportal.com/) which provides insights at various scales (river basin,
